VACUUM CLEANING DEVICE.

Specification of Letters Patent.

Patented Nov. 12, 1912.

' Application filed August 7, 1911. Serial No. 642,778.

. To all whom it may concern Be it known that I, JAMES J. SLEVIN, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Vacuum Cleaning Devices for Cleaning Animals, of which the followin is a specification.

y invention relates to an im roved device for cleaning animals and or the removal of the particles of dust, .dirt and hair, by the vacuum process, and the same is an improvement upon the device shown and described in my application for Letters Patent filed February 13th, 1911, Serial No. 608,435.

In the device of the said application, the series of bristles and the blades formin the curry-comb members were arrange across the foundation and at right angles to the line of the slot therein, and in alternating groups; that is to say, the curry comb members were arranged between the bristles. In a series of experiments, I have demonstrated that this arrangement is not as advantageous for the thorough cleaning of the animals, as is the arrangement of the present application; and with the object of making the device as perfect and as efficient as possible, I provide in the device of my present invention, for arranging the bristles in masses at the ends of the foundation block; or in other words, across the ends of the block. The curry comb blades are arranged between the masses of bristles and spaced apart from one another and from the bristles and also arranged at right angles to the line of the slot in the foundation.

In the device of my present invention, I connect an intake nozzle to the upper surface of the foundation and provide an opening therein and slots from this opening and also;,a recess, and the recess and slots come below the curry-comb blades or members, and I also prefer to form the curry-comb members of U-shape, ccnnectin them at their respective ends to the foun ation, and

I prefer to cut away the central portion of ,device of my improvement.

the bottom of each U-shaped member so that there is a free entrance for the air not only between the series of bristles and between the curr -comb blade members, but in the center 0 each blade member.

In the drawing, Figure '1 is a plan and Fig. 2 a side elevation representing the ig. 3 is an in- .This band assists materiall the bristles and in preventlng them breakverted plan. Fig. 4 a central longitudinal section at the dotted line 01:, m, Fig. 1, and Fig. 5 is a detached section longitudinally and centrally through the U-shaped currycomb blade members at one end.

Similar letters and numerals of reference indicate the same parts in all the figures.

a represents the foundation block of my improved vacuum. cleaning device. This block is preferably of wood. It is provided centrally with a recess 3, which from the under surface is stepped down. Below the surface of the recess there is a slot or slots 2 and a central opening which communicates through the block a with the intake nozzle b. This intake nozzle is provided with a plate I) by which it is secured to the upper surface of the foundation block a, and I prefer to make the plate 6 with upturned and slotted ends and to provide an adjustable strap handle 6 the parts of which pass through the said slots. This construction permits of the introduction of the hand of the attendant or operator above the plate 6 and'noz'zle b and beneath the strap handle 12 so that the implement is readily and securely handled for the cleaning work.

0 represents an end of flexible hose, and c a coupling attached thereto and introduced into the intake nozzle 6. Regardless of the, exact construction illustrated for these parts, they may be suitably made in any desired manner.

d and d represent the bristles in series at the respective ends of the foundation block a, and I prefer to provide this foundation block 'a. with a skirt 6 preferably in the form of a metalband secured around the block and extending below the under surface thereof and appreciably around the bristles. in supporting ing down or being spread too much in use, or in other words, holding up and stiffening the bristles for their work. This band or skirt 6 is advantageously endless and formed of some light metal like aluminum.

f represents the several serrated currycomb blades which in cross section, as shown in Fig. 4, may be of U-shape, that is with a base and two parallel blades atright angles to the base, and the edges of the blades formed with teeth. I prefer, as shown in Fig. 5. to corrugate the edges of these blades and byso doing produce teeth with rounded points and bases, which are eflicient for '15 centerrecess of the foundation and at right the work performed and not injurious to the skin of the animal being cleaned, and at the same time I prefer to form one of the angles to the slot 2. These curry-comb blade members are spaced apart and also preferably spaced from the adjacent edges of the bristle groups 03 d, and at the respective ends of these groups there is nothing to interfere upon the opposite sides of the -implement with the free entrance of air, or in other words, a free air draft as produced by the suction in a vacuum cleaning implement, this air draft being in line with' the blades of the curry-comb members and with thespaces between the members.

In the operation of the device of my improvement, the implement is held in the hand,-that is with the hand between the strap handle and the under surface of the intake nozzle and its plate is moved backward and forward over the body of the animal to be cleaned in a direction agreeing with the lengthwise direction of the implement, so that in one direction of movement the bristles d are in advance and the bristles (Z follow, while in the opposite direction, the bristles d are in advance and the bristles (1 follow.

I have found as the result of experiments with the actual use of this device, that it is exceeding eflicient; that the work is quickly and thoroughly done and without discomfort to either the operator or the animal.

In Figs. 3 and 4 I have shown some of the curry-comb blades f as formed with a .bottom portion and of U-shape in cross sec tion, and the other of the curry-comb blades f as separate blades with flat foot supports secured by screws to the foundation. I do not limit my invention by the precise construction of the curry-comb blades or by the manner of fastening the same to the,

foundation, as the forms illustrated are equivalent and other forms may answer the purpose equally well.

I claim as my invention: 1. A-vacuum cleaning devicefor cleaning animals, comprising a foundation of suitable material to be manipulated by hand and provided with an opening therein, an intake nozzle suitably secured to one surface of said foundation, series of bristles secured to the opposite side of said foundation and in groups at the respective ends thereof so as to form brushes, and series of blades forming curry-comb members secured to the said surface of the foundation and arranged in a spaced apart relation across the opening in said foundation and between the brushes at the respective ends thereof, and also at right angles to the longest axis of thefoundation.

2. A-vacu'um cleaning device for cleaning animals, comprising a foundation of suitable material to be manipulated by hand and provided with an opening therethrou h and a transverse central recess, an inta (e .nozzle suitably secured to one surface of said foundation, series of bristles secured to the opposite side of said foundation and in groups at the respective ends thereof so as to form brushes, series of removable blades forming curry-comb members secured to the same surface of the foundation and arranged in a spaced apart relation across the recess in said foundation and between the brushes at the respective ends thereof and also at right angles to the longest axis of the foundation, and a skirt in the form of a metal band or late extending around the foundation and extending down approximately over the bristles of the brushes at the ends of thefoundation.
